* Debian: Fixed packaging error about invalid "Source-Version"
  substitution variable.
* Debian: Raised Debian compatibility level to Debian 9 "Stretch".

1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5 schoenebeck 3082 - Removed code duplication in SFZ file loading code.
6     - Added support for sfz extension opcode 'script' which may be used to
7     load real-time instrument script file (NKSP script language).
8 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
10 persson 3291 - sfz parser: allow missing space between header and opcode
11 persson 2856
12 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
13 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
14     cutoff settings.
15 schoenebeck 3302 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
16     all if an up-pitch of more than 40 semi tones was requested (I don't
17     think there is any stock gig sound that requires this behavior to
18     resemble its original sound).
19 schoenebeck 3328 - Added support for controlling whether the individual EGADSR stages may
20     be aborted (as LinuxSampler extension to the original GigaStudio 4
21     format).
22 schoenebeck 3072
23 persson 2837 * general changes:
24     - fixed printf type errors (mostly in debug messages)
25 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
26 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
27     allowing to sort data efficiently in real-time safe manner.
28     - RTList class: added methods for moving/inserting elements to arbitrary
29     position within a list.
30     - RTList class: added method fromPtr() for creating an Iterator object from
31     a raw element pointer.
32     - Attempt to partly fix resetting engine channels vs. resetting engine, an
33     overall cleanup of the Reset*(), ConnectAudioDevice(),
34     DisconnectAudioDevice() API methods would still be desirable though,
35     because the current situation is still inconsistent and error prone.
36 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
37     being directly assigned to a keyboard key. This allows more fine graded
38     processing of voices, which is i.e. required for certain instrument
39     script features.
40 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
41     (CC #64) events.
42     - Fix: Release trigger voices can now also distinguish correctly between
43     note-off and sustain pedal up events.
44 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
45     (while slow rate of crossfade smoother is preserved) to allow quick
46     volume and pan changes by instrument scripts for instance.
47 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
48     properly and thus were ignored for certain uses.
49 schoenebeck 3018 - Added new C++ API method
50     VirtualMidiDevice::SendChannelPressureToSampler().
51 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
52     sub threads is 16-byte aligned
53 schoenebeck 3054 - fixed numerous compiler warnings
54 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
55 schoenebeck 3290 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
56     fixes potential undefined behavior.
57 schoenebeck 3306 - Fixed Note object leak when triggering notes on keys which did not
58     have a valid sample mapped (fixes bug #252).
59     - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
60 persson 2837
61 schoenebeck 2866 * packaging changes:
62     - removed unnecessary dependency to libuuid
63     (originated by libgig's usage of it)
64 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
65     auto detect whether it (sh/c)ould output its messages in color.
66 schoenebeck 3352 - Debian: Fixed packaging error about invalid "Source-Version"
67     substitution variable.
68     - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
69 schoenebeck 2866
70 schoenebeck 2871 * Real-time instrument scripts:
71     - Implemented scheduler for delayed MIDI events and for suspended scripts.
72     - Built-in script function "wait()": implemented support for function's
73     "duration-us" argument, thus scripts using this function are now
74     correctly resumed after the requested amount of microseconds.
75     - Built-in script function "play_note()": implemented support for
76     function's "duration-us" argument, thus notes triggered with this
77     argument are now correctly released after the requested amount of
78     microseconds.
79     - Fix: script events were not cleared when engine channel was reset,
80     potentially causing undefined behavior.
81     - Fixed crash which happened when trying to reference an undeclared
82     variable.
83 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
84     special value -1 for "duration-us" argument, which will cause the
85     triggered note to be released once the original note was released.
86 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
87     - Added new API method ScriptVM::syntaxHighlighting() which provides
88     a convenient syntax highlighting backend for external instrument
89     script editor applications.
90 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
91     - Extended parser issues to provide not only first line and first
92     column, but also last line and last column of issue (thus marking
93     the precise span of the issue within the source code).
94 schoenebeck 2902 - Reload script automatically after being modified by an instrument
95     editor.
96 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
97     like "on note end on".

102     - Implemented built-in script function "change_reso()".
103     - Implemented built-in script function "event_status()".
104     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
105     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
106     "event_status()" function.
107     - NKSP language: Added support for bitwise operators ".or.", ".and."
108     and ".not.".
109     - NKSP language scanner: Fixed IDs matching to require at least one
110     character (i.e. when matching function names or variable names).
111     - NKSP language scanner: disabled unusued rules.
112 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
113     be distinguished engine internally from "real" MIDI note on/off
114     events in order to avoid misbehaviors like hanging notes.
115 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
116     - Implemented built-in script variable "$NKSP_REAL_TIMER".
117     - Implemented built-in script variable "$NKSP_PERF_TIMER".
118     - Implemented built-in script variable "$ENGINE_UPTIME".
119 schoenebeck 2945 - Implemented built-in script function "inc()".
120     - Implemented built-in script function "dec()".
121     - NKSP language fix: division expressions were evaluated too often.
122     - NKSP language fix: string concatenation operator was right
123     associative instead of left (to right).
124 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
125     (i.e. "if end if").
126 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
127     - Implemented built-in script variable "$NI_CALLBACK_ID".
128     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
129     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
130     - Added support for read-only built-in variables (respectively
131     handled by the script parser).
132     - Added built-in script constant "$NI_CB_TYPE_INIT".
133     - Added built-in script constant "$NI_CB_TYPE_NOTE".
134     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
135     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

138     - Implemented built-in script function "change_decay()".
139     - Implemented built-in script function "change_release()".
140 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
141     synthesis parameter changes immediately in case the respective note
142     was triggered at the same time, instead of scheduling the parameter
143     change, especially because it would cause some parameter types's
144     changes either to be ramped (i.e. change_vol()) or other types even
145     to have not effect at all (i.e. change_attack()).
146 schoenebeck 2965 - Implemented built-in script function "sh_left()".
147     - Implemented built-in script function "sh_right()".
148 schoenebeck 2970 - Implemented built-in script function "min()".
149     - Implemented built-in script function "max()".
150 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
151     was loaded.
152     - NKSP built-in wait() script function: abort script execution if
153     a negative or zero wait time was passed as argument (since this is
154     a common indication of a bug either of the script or even of the
155     engine, which could lead to RT instability or even worse).
156 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
157     threatening scripts.
158 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
159 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an

169     - Implemented built-in script function "fade_in()".
170     - Implemented built-in script function "fade_out()".
171     - Fixed acceptance of wrong data type of parameters passed to built-in
172     script functions "change_vol()", "change_tune()", "change_pan()",
173     "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
174     "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
175     "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
176 schoenebeck 3193 - Added built-in script function "get_event_par()" and implemented some
177     of its possible parameter selections.
178     - Added built-in script function "set_event_par()" and implemented some
179     of its possible parameter selections.
180 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
181 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.

184 schoenebeck 3214 - Implemented built-in script function "change_velo()".
185     - Implemented built-in script function "change_note()".
186 schoenebeck 3218 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
187     intuitive behavior if used in combination with "change_vol_time()" or
188     "change_tune_time()" respectively: now tuning/volume changes are only
189     assigned (without delay) immediately to a new note if the respective
190     timing function has not been called before, otherwise the volume/tuning
191     changes are automatically faded (before, only the event's time stamp was
192     relevant).
193 schoenebeck 3221 - Implemented built-in script function "array_equal()".
194     - Implemented built-in script function "search()".
195     - Implemented built-in script function "sort()".
196     - NKSP Fix: Never suspend "init" event handlers.
197 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
198     available for gig format engine).
199 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
200     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
201     - Implemented built-in script function "change_vol_curve()".
202     - Implemented built-in script function "change_tune_curve()".
203 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
204     offset with argument 3, where special value -1 means to use the regular
205     sample offset as defined by the instrument file.
206 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
207     - Built-in variable $EVENT_NOTE is now a read-only variable.
208     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
209     - built-in "play_note()" function now accepts -2 for its fourth argument
210     (note duration) which means the life time of the note shall be sticked
211     to the requested note number of argument 1.
212     - Fix: built-in "play_note()" function now returns 0 as result value if
213     -1 was passed for its fourth argument (note duration) and the respective
214     parent note is already gone.
215 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
216 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
217     - NKSP language: Raise parser warning if array variable is accessed with
218     an index that exceeds the array's size.

225     "init" event handlers.
226 schoenebeck 3285 - Print a time stamp along to each call of built-in function "message()".
227     - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
228     to retrieve all code blocks filtered out by the preprocessor.
229 schoenebeck 3293 - Added built-in script function "fork()".
230     - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
231     - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
232     - Fixed potential crash when accessing dynamic built-in array variables.
233 schoenebeck 3296 - Added built-in script function "callback_status()".
234     - Added built-in constant $CALLBACK_STATUS_TERMINATED.
235     - Added built-in constant $CALLBACK_STATUS_QUEUE.
236     - Added built-in constant $CALLBACK_STATUS_RUNNING.
237 schoenebeck 3303 - Removed max. value limitation of built-in functions "change_attack()",
238     "change_decay()" and "change_release()" to i.e. allow passing 2000000
239     for doubling the respective time.
240 schoenebeck 3308 - NKSP script editor syntax highlighting API: Fixed app termination due
241     to a lexer start condition stack underrun.
242     - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
243     USE_CODE_IF_NOT() preprocessor statements.
244 schoenebeck 3311 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
245     can be set to disable all subsequent built-in "message()" function calls
246     on preprocessor level.
247 schoenebeck 3316 - Implemented built-in script function "change_sustain()".
248 schoenebeck 3332 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
249     to avoid the editor app to crash on ill-formed text input.
250 schoenebeck 3335 - Added built-in script function "change_pan_time()".
251     - Added built-in script function "change_pan_curve()".
252 schoenebeck 2871
253 schoenebeck 3050 * Instruments DB:
254     - Fixed memory access bug of general DB access code which lead to
255     undefined behavior.
256 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
257     - The instrument DB path of linuxsampler's --create-instruments-db argument
258     is now optional, if it is missing, then a default location is used.
259 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
260     - Added support for scanning Sound Font (.sf2) files.
261 schoenebeck 3101 - Fixed undefined DB transaction behavior.

302 persson 2382
303 persson 2086 * general changes:
304 iliev 2012 - Refactoring: moved the independent code from
305     the Gigasampler format engine to base classes
306 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
307     respective profiling code is currently broken
308 schoenebeck 2053 - Introduced support for optional environment variable
309     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
310     where the sampler shall look for instrument editor plugins
311     (patch by Luis Garrido, slightly modified).
312 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
313     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
314     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
315     note (in this implementation of the sampler its simply hard routed to
316     the 1st effect send of the sampler channel, no matter what the actual
317     effect type is)
318     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
319     note (in this implementation of the sampler its simply hard routed to
320     the 2nd effect send of the sampler channel, no matter what the actual
321     effect type is)
322 schoenebeck 2124 - implemented support for internal LADSPA effects
323 schoenebeck 2140 - raised limit of program change queue from 100 to 512
324     (as suggested by Alex Stone)

326 iliev 2296 - experimental support for per voice equalization
327 iliev 2306 - added command line option --exec-after-init
328 schoenebeck 2330 - Introduced new C++ API method:
329     EngineChannel::InstrumentFileName(int index)
330     allowing to retrieve the whole list of files used for the loaded
331     instrument on an engine channel (a.k.a. part). Some GigaStudio
332     instruments for example are splitted over several files like
333     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
334 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
335     - Added new C++ API method Sampler::GetGlobalMaxStreams().
336     - Added new C++ API method Sampler::SetGlobalMaxVoices().
337     - Added new C++ API method Sampler::SetGlobalMaxStreams().
338 schoenebeck 2377 - Various "const" and "restrict" optimizations.
339 persson 2382 - all engines: add pan CC value to instrument pan parameter before
340     applying panning, instead of using two separate pan functions in
341     series (#182)
342 persson 2427 - added a lock guard class for exception safe mutex handling and
343     used it everywhere appropriate
344 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
345     - Exposed scale tuning to C++ API (along to the already existing standard
346     SysEx way).
347 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
348     and broken for ppc64. (Seq_cst loads and stores are actually not
349     used in LS, so the bug wasn't noticable.)
350     - lsatomic.h: added ARMv7 support
351 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
352     added various new C++ methods for this new feature / design change, old
353     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
354     as deprecated but are still there and should provide full behavior
355     backward compatibility).
356     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
357     unsafe and caused compilation error with clang 2.x).
358 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
359 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
360     sampler from the command line by providing LSCP aware features.
361 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
362     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
363     - VirtualMidiDevice: Added support for pitch bend.
364 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
365     polyphonic key pressure events (so far polyphonic pressure was not

769     after MIDI/audio device creation failure
770 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

772     took the full preloading time and on 1st program change the respective
773     instrument was completely reloaded again.
774 persson 2277 - fixed handling of rapid bank select and program change messages
775     sent to the same sampler channel (patch from the Open Octave

796 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
797     (fixes #208)
798 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
799     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
800     practically irrelevant, however it caused problems with the new LSCP
801     shell's auto completion feature).
802 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
803     after each other (fixes #231).

853 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
854     be switched on by command line option "--stacktrace" (the automatic
855     stacktrace mechanism seems to be broken on most systems at the moment)
856 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
857     a pointer to the launched InstrumentEditor object
858 schoenebeck 1876 - added optional 3rd party user data parameter for following

880 persson 1748 jack_client_new
881 iliev 1829 - added (experimental) CoreAudio driver
882 persson 1888 - applied old fixes to the ASIO driver that were included in the
883     previous binary release but accidentally never committed to CVS
884     (fixes #117)
885 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
886     win64)

900     exception when getting parameters from a disconnected device
901 schoenebeck 1599
902 persson 1651 * MIDI driver:
903     - added JACK MIDI driver
904 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
905     want to (mis)use it for some purpose ("fixed" in all current MIDI
906     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
907 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,

922     instrument database compilable
923 schoenebeck 1930 - added instrument database support on Windows
924     works with both standalone mode and VST plugin.
925     the instruments DB file is located in
926     %USERPROFILE%\.linuxsampler\instruments.db which allows different
927     databases for each windows user
928     if no DB is present it automatically creates the .linuxsampler subdir
929     and then creates an empty DB
930 persson 1943 - fixed recursive import, which was broken on Windows
931 iliev 1603
932 persson 1644 * Gigasampler format engine:
933     - fixed a memory leak that could happen when a channel was deleted

935 persson 1646 - made it possible to load an instrument even if the audio thread
936     isn't running
937 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
938     enough for piano gigs with pedal noise samples
939 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
940     respective FX send MIDI controller was used
941 schoenebeck 1724 - added support for GM global device volume SysEx message
942 schoenebeck 1762 (can be selected at compile time to either apply globally to the
943     whole sampler [default] or only to the sampler channels that are
944     connected to the respective MIDI input port the SysEx message arrived
945     on)
946 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
947     sometimes wrongly killed in the same buffer, causing no sound to
948     be played
949 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
950     which is usally used to switch a part between chromatic sounds and
951     drumkit sounds (as opposed to their common default setting of MIDI
952     part 10 being a drumkit part and all other ones chromatic parts), in
953     LS however one can switch between the first 16 MIDI instrument maps
954     defined for the sampler
955 persson 1764 - made it possible to create multiple sample channels even if the
956     audio thread isn't running
957 persson 1844 - fixed crash when removing channel with active voices (#116)
958 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
959     un-cache the respective sample if it's really not used by any
960     sampler engine anymore
961     - re-cache samples in case they were changed by an instrument editor,
962     e.g. when a sample was added while playing (#82)
963 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
964     same time stamp as the voice's note-on event and occured both in the
965     same audio fragment cycle (fixes bug #112)
966 persson 1858 - added support for the "fine tune" and "pitch bend range"
967     instrument-level gig parameters
968     - fixed minor artifacts in pitch bend handling
969 schoenebeck 1860 - added support for GS Reset SysEx message
970 persson 1862 - allow gig files to use unlimited downward pitch shifting
971     - added a limit check for upward pitch shifting
972 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
973     note was silent
974 persson 1923 - fixed crash happening when a pitch bend event arrived at the
975     same time a new instrument was loading
976 persson 1644
977 schoenebeck 1687 * LSCP server:
978     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
979     react on MIDI data arriving on certain sampler channels (so far only
980     Note-On and Note-Off events are sent via this LSCP event)
981 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
982     react on MIDI data arriving on certain MIDI input devices (so far only
983     Note-On and Note-Off events are sent via this LSCP event)
984 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
985     SET DB_INSTRUMENT FILE_PATH

987     frontends to send MIDI messages to specific sampler channel
988     - added two additional fields to GET FILE INSTRUMENT INFO command -
989     KEY_BINDINGS and KEYSWITCH_BINDINGS
990 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
991     was incorrect
992 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
993 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
994     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
995     be triggered respectively
996     - added new LSCP command "SET STREAMS" to globally alter the maximum
997     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
998     which will be triggered respectively
999 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1000     a gigedit file dialog is opened)
1001 iliev 1848 - close all connections when LSCPServer is deleted
1002 iliev 1882 - hard close of all sockets on exit

1020 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1021 iliev 1847 - fixed crash when changing the audio output device of a sampler
1022     channel with loaded instrument and start playing notes
1023 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
1024 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit

1026 persson 1889 - fixed a memory management error which could cause a crash when a
1027     plugin was unloaded
1028 persson 1896 - bugfix: two private structs had the same name, which could cause

1043     - bugfix: the thread used by an editor plugin didn't die when the
1044     editor closed
1045 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1046     out all the space. operator--() did not apply size_mask after
1047     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1048     order to avoid problems with the _NonVolatileReader functions.
1049     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1050     GetWriteSpace(). Since this function is currently only used in
1051     the stream's qsort() compare function, it didn't trigger any
1052     bugs.
1053     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1054     24bit mode too. Faster method to read 24bit words on little
1055     endian machines (x86): replaced 3 byte reads + shifts with a 1
1056     unaligned 32bit read and shift
1057     - experimental support for MS Windows (MIDI input via MME, AUDIO
1058     output via ASIO)
1059     - made handling of SIGINT signal (Ctrl-C) a bit more robust

1062     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1063 persson 1455
1064 senoner 1500 * AUDIO driver:
1065 persson 1534 - added Windows ASIO low latency audio driver
1066 senoner 1500
1067 senoner 1485 * MIDI driver:
1068 schoenebeck 1495 - added MME Windows MIDI driver
1069 senoner 1485
1070 schoenebeck 1471 * LSCP server:
1071     - added support for Windows style path / filenames, however with
1072     forward slash path separators instead of backslash
1073     (i.e. "C:/foo/bar.gig")
1074 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1075     apostrophes as well
1076 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1077     "LIST FILE INSTRUMENTS <file>" and
1078     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1079     about an arbitrary instrument file on the system where the sampler is
1080     running on
1081 schoenebeck 1471
1082 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1083 schoenebeck 947
1084 schoenebeck 1065 * packaging changes:
1085 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1086     API header files anymore
1087 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1088     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1089 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1090     capable to execute our autoconf environment, thus no need anymore
1091     to maintain the compile time configuration file (osx/version.h) for
1092     OSX manually (patch by Toshi Nagata)
1093 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1094     parameters
1095 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1096     C++ API header files, all implementation internal global definitions
1097     are now in global_private.h
1098     - atomic.h is not exposed to the C++ API anymore
1099     - no need to include config.h anymore for using LS's API header files
1100     - fixed warnings in API doc generation
1101 schoenebeck 1065
1102 schoenebeck 947 * general changes:
1103     - replaced the old, confusing MIDI program change mechanism by a
1104     flexible MIDI instrument mapper which allows to map arbitrary
1105 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1106 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1107     loaded on the respective channel when such MIDI program change
1108     messages arrive, beside that, each entry allows to define a life-time
1109     strategy for the instrument, so the user can define whether the
1110     instrument should i.e. be permanently loaded (to be able to switch
1111     quickly among sounds) or i.e. loaded just on demand when the
1112     respective program change arrives (to safe RAM space), as well as a
1113     global volume factor for each entry, so the user can adjust the volume
1114     dynamic of his mapped instrument collection without having to modify
1115 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1116     MIDI instrument maps and assign each sampler channel individually
1117     a certain map, so that i.e. separation of normal instruments and
1118     drumkits is possible
1119 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1120     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1121 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1122     due to a constant size RingBuffer FIFO which is now replaced by a
1123     dynamic (unlimited) size std::list FIFO
1124 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1125     output channels for being processed by external effect processors
1126     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1127     controllers
1128 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1129 iliev 1130 - Implemented new, improved notification system
1130 schoenebeck 1149 - fixed compilation errors regarding OSX
1131     (patch by Toshi Nagata)
1132 iliev 1161 - implemented instruments database
1133 iliev 1345 - added support for escape sequences to the instruments database
1134 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1135     within the sampler's process (by using instrument editor plugins),
1136     you'll notice the new "Registered instrument editors:" message on
1137 schoenebeck 1407 startup, added a new LSCP command:
1138     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1139 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1140     given sampler channel, the plugin path can be overridden at compile
1141     time with ./configure --enable-plugin-dir=/some/dir
1142 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1143     in the sampler's process to safely edit instruments while playing
1144     without a crash (hopefully) by either suspending single regions
1145     wherever possible or if unavoidable whole engine(s)
1146 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1147     policy and priority on thread level, set a minimum stack size for
1148     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1149     threads simply inherited properties of starting thread instead of
1150     setting their own policy and priority
1151 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1152     main process did not wait for the stack trace process to finish
1153     its output
1154 persson 1248 - fixed some minor memory leaks
1155 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1156     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1157 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1158     register, to avoid relocations in the text segment at runtime)
1159 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1160 schoenebeck 947
1161     * MIDI driver:
1162     - dispatch bank select (MSB and LSB) messages
1163    
1164 schoenebeck 1049 * audio driver:
1165     - the ALSA audio output driver parameters now reflect the correct
1166     parameter value ranges for the respective selected sound card
1167     (patch by Till Wimmer, a bit fixed and extended)
1168    
1169 persson 951 * Gigasampler format engine:
1170     - if a filter is used and EG2 finishes before EG1, let the voice
1171     die when EG2 has finished (this fixes a problem with clicks and
1172     voice starvation for some gigs)
1173 persson 1038 - playback is no longer disabled during instrument loading
1174     - all notes playing on a channel that changes its instrument keep
1175     playing with the old instrument until they get a note off
1176     command
1177 persson 1039 - EG fix: a release value of zero could cause noises or crash
1178 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1179 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1180     above max sustain level, which means that there is a decay phase
1181     even if sustain is 100%
1182 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1183     noises or crashes
1184 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1185 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1186     supplied to the configure script (fixes #46)
1187 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1188     instead of a fix value
1189 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1190     127 (solo mode) only kill voices if the respective mode really
1191     changed
1192 persson 951
1193 schoenebeck 1244 * LSCP server:
1194     - fixed compile time error for old Bison versions
1195     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1196 schoenebeck 1245 - parser now supports extended ASCII character set
1197     (up to ASCII code 255, i.e. includes now umlauts and accents)
1198     - filename arguments in LSCP commands now allow to use escape
1199     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1200     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1201     code value like \xf2) (fixes bug #24)
1202 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1203     least one of their text-based parameters (i.e. name, description):
1204     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1205     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1206     "SET DB_INSTRUMENT_DIRECTORY NAME",
1207     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1208     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1209     "FIND DB_INSTRUMENT_DIRECTORIES"
1210 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1211     occured, the unexpected character and the actually expected, possible
1212     character(s), the latter only if less than 5 possibilities)
1213 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1214     settings
1215 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1216     of strings were treated as being one string containing commas
1217     (fixes #57)
1218 schoenebeck 1244
1219 iliev 959 * Bug fixes:
1220     - fixed crash occurring on certain LSCP scripts (Bug 39)
1221 persson 1038 - another thread safety fix for lscp "load engine" and "set
1222     channel audio output device"
1223 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1224     on a sampler channel with connected MIDI device
1225 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1226     device connected to a sampler channel to number less then or equal
1227     to the index of the port to which the sampler channel is connected.
1228 iliev 1296 - The previous bindings were not been disconnected when altering
1229     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1230     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1231 iliev 1297 - The active stream/voice count statistic was incorrect.
1232 iliev 1298 - notification events were not been sent for some sampler
1233     channel changes
1234 iliev 1305 - added default min and max values to restrict the number of allowed
1235     audio output channels and MIDI input ports
1236 iliev 1306 - the connection to the PCM interface is now closed when destroying
1237     an audio output device
1238 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1239 iliev 959
1240 schoenebeck 1221 * test cases:
1241     - updated and fixed (haven't been touched in a while)
1242    
1243 schoenebeck 937 Version 0.4.0 (24 November 2006)
1244 persson 696
1245 schoenebeck 697 * packaging changes:
1246 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1247     to post-(un)install steps; added devel package for liblinuxsampler;
1248     to linuxsampler.spec (RPM)
1249 schoenebeck 697 - install necessary development header files for allowing 3rd party
1250     applications to link against liblinuxsampler
1251     - liblinuxsampler's API documentation can be generated with 'make docs'
1252     (Doxygen required)
1253 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1254     implementation (currently either an integer math solution or a
1255     di-harmonic approximation), automatic detection can be overriden
1256     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1257     configure script argument though (mandatory for cross-compilation)
1258 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1259     provided some on his own (as CXXFLAGS)
1260 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1261     messages
1262 schoenebeck 852 - added compile time options to allow disabling the various audio and
1263     MIDI drivers
1264 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1265     (patch by Ebrahim Mayat)
1266 schoenebeck 697
1267 persson 696 * Gigasampler format engine:
1268 schoenebeck 738 - extensive synthesis optimization
1269     (reimplementation of EGs and LFO(s), removed synthesis parameter
1270     prerendering and the synthesis parameter matrix in general, splitting
1271     each audio fragment into subfragments now where each subfragment uses
1272 persson 830 constant pitch and filter coefficients. The volume coefficient is
1273     linearly interpolated inside a subfragment, unless
1274     --disable-interpolate-volume is set.)
1275 persson 696 - fine tuning of the EG modulation parameters
1276 persson 729 - improved filter cutoff calculation by adding support for the
1277     following gig parameters: Cutoff freq (used when no cutoff
1278     controller is defined), Control invert, Minimum cutoff, Velocity
1279 persson 791 curve and Velocity range. The keyboard tracking now scales
1280     cutoff frequency instead of resonance.
1281 persson 877 - added support for gig parameter Resonance.
1282 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1283 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1284     which can be overridden with --enable-global-attenuation
1285 persson 783 - EG fixes: made the length of "attack hold" stage more
1286     accurate. Release stage can now start before attack stage
1287 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1288     time now has a minimal value to prevent clicks.
1289 persson 799 - fixed pitch changes larger than one octave
1290 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1291     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1292     all modes can be altered via standard GM messages, that is CC5 for
1293     altering portamento time, CC65 for enabling / disabling portamento
1294     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1295 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1296     parameter) and crossfade
1297 persson 831 - added support for the "attenuation controller threshold" gig
1298     parameter
1299 persson 832 - added smoothing of volume changes caused by control change
1300     messages
1301 persson 865 - sample loop parameters are now taken from the DimensionRegion
1302     instead of the wave chunk
1303     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1304     not equal to a power of two
1305 persson 877 - reimplementation of the filter algorithm. The new filter is more
1306     accurate and supports all gig filter types, including bandreject
1307     and lowpass turbo.
1308 persson 903 - real support for 24 bit samples - samples are not truncated to
1309     16 bits anymore
1310     - support for aftertouch (channel pressure, not polyphonic
1311     aftertouch)
1312 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1313     amplifying from 0)
1314 persson 696
1315 schoenebeck 711 * LSCP server:
1316     - fixed application exit on broken pipe error (fixes bug #20)
1317 iliev 793 - fixed the notification messages delay due to lack of
1318     network activity (fixes bug #26)
1319 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1320     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1321 schoenebeck 711
1322 schoenebeck 838 * audio driver:
1323     - added aRts audio output driver (by no means RT safe)
1324    
1325 schoenebeck 775 * MIDI driver:
1326     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1327     messages several times instead of once
1328 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1329     for events (i.e. for offline rendering based MIDI drivers)
1330 persson 922 - added checks for bad MIDI data
1331 schoenebeck 775
1332 schoenebeck 900 * linuxsampler application:
1333     - show available sampler engine types on startup
1334    
1335 schoenebeck 705 * general changes:
1336     - support for muting sampler channels and solo mode of the same, two new
1337     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1338     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1339     introduced for this, the behavior is the same like on a mixer console
1340 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1341     --enable-process-muted-channels which can be used to enable the
1342     processing of muted channels.
1343 iliev 777 - support for sostenuto pedal
1344 iliev 779 - support for monitoring the total number of active voices
1345 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1346     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1347 persson 835 - fixed some memory management errors
1348 persson 841 - fixed some concurrency problems that could lead to crashes when
1349     LSCP commands were executed
1350 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1351     sampler channel (fixes bug #36)
1352 schoenebeck 705
1353 schoenebeck 692 Version 0.3.3 (15 July 2005)
1354 schoenebeck 686
1355     * packaging changes:
1356     - fixed compilation with gcc 4.0
1357    
1358 schoenebeck 687 * Gigasampler format engine:
1359     - LFO preprocessing was performed even though the respective LFO was
1360     disabled by the instrument patch (minor efficiency fix)
1361 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1362     for volume ramp downs in the same fragment (needed for current voice
1363     stealing implementation) then simply inform the user with a warning
1364     about possible click sounds and reduce the volume ramp down
1365     appropriately instead of cancelling the audio device connection
1366 schoenebeck 687
1367 schoenebeck 677 Version 0.3.2 (24 June 2005)
1368 schoenebeck 609
1369     * packaging changes:
1370     - updated autotools build files to compile on OS X
1371     (conditional compilation of CoreMIDI and MidiShare drivers)
1372 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1373     './configure --disable-asm' (definitely not recommended)
1374 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1375     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1376     (due to 'dist-bzip2' automake option)
1377 schoenebeck 649
1378     * Gigasampler format engine:
1379     - support for the gig parameters for "release velocity response" curves
1380     - fine tuning of the EGADSR envelope
1381     - volume of release triggered samples now depends on note-on velocity,
1382     note length and gig parameter "release trigger decay" instead of
1383     note-off velocity.
1384 schoenebeck 663 - revised voice stealing
1385     (fixes crash and endless loop caused by voice stealing)
1386 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1387 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1388     instead of when the respective voice is actually launched
1389     (fixes undefined behavior if stolen voices belonged to a key group -
1390     this case was followed by a "killed voice survived" error message)
1391 schoenebeck 669 - fixed minor issue with null/silence samples
1392     (those stole voices even though they don't need a voice at all which
1393     resulted in "voice stealing didn't work out" messages)
1394 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1395     instrument or audio output device change
1396 schoenebeck 654
1397 schoenebeck 620 * LSCP server:
1398 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1399 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1400 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1401 schoenebeck 609
1402 schoenebeck 668 * linuxsampler application:
1403     - added command line parameters --lscp-addr and --lscp-port to override
1404     default IP address and port of LSCP server
1405    
1406 schoenebeck 579 Version 0.3.1 (24 May 2005)
1407    
1408     * initial release
